Wordpress – HTML文档不是从第一行开始 [英] Wordpress – HTML document does not start at line one

问题描述

我已经为这个问题苦苦挣扎很长时间了，但是我找不到真正的解决方案.问题是< !DOCTYPE html etc...不在第一行开始，而是在开始前留了四行空白.

I've been struggling with this problem for a long time now, but I cannot really find the solution. The problem is that < !DOCTYPE html etc... does not start at the first line, but leaves four blank lines before it starts.

我的所有文件(header.php，index.php等)在开始之前都没有换行符.

All my files (header.php, index.php etc) have no line breaks before they start.

任何有类似问题/经验的人吗?这将是巨大的帮助！

Anyone with any similar problems/experiences out there? It would have been of huge help!

推荐答案

这通常不是由 leading 引起的，而是由 trailing 空格引起的.许多旧的PHP代码仍然会在最后关闭代码，然后这些代码常常会出现一个换行符:

This is most often not caused by leading but by trailing whitespace. Lots of old PHP code still closes down code at the end, which then all too often has a stray newline:

<?php

  // Lot of source code

?>   <----- and a newline here which is the culprit!

为避免此问题，请不要使用?>关闭文件-PHP不需要它，它将在EOF处停止解析，因此在输出中隐式避免了这种垃圾".

To avoid this issue, never close files with ?> - PHP doesn't need it and will just stop parsing at EOF, thus implicitly avoid this 'garbage' in the output.

至于找到导致它的文件-祝你好运，我将从为此组合任何自定义扩展名开始，然后删除所有可以找到的?>标记.

As for finding the files causing it - good luck, I'd start with combing any custom extensions for this and just removing all ?> markers that you can find.

或者，您可以通过向index.php添加单个ob_start()调用来修复"它，然后在包含执行ob_end_clean()的doctype的模板中-将所有中间输出放入输出缓冲区，然后将其丢弃.

As an alternative, you can probably 'fix' it by adding a single ob_start() call to your index.php, and then in the template containing the doctype executing ob_end_clean() - this puts all intermediate output in the output buffers, and then trashes it.
